(Cl. 297148) ABSTRACT OF THE DISCLOSURE A high chair having a pair of leg frames to which a U-shaped back rest and tray support is connected. Said leg frames also support a rod carrying a sheet-metal step for mounting said step on said leg frames.

This application is -a continuation of our copending application Ser. No. 403,456, filed Oct. 13, 1964, and now abandoned.

This invention relates to a high chair and has for its object the provision of a high chair of attractive appearance, which can be economically manufactured largely from sheet-metal and metal-tubing, and which will provide a construction that will permit a child to be easily placed therein and removed therefrom. It is a further object of the invention to provide a high chair having a tray which can be easily applied to and removed from said chair and which can be releasably locked in a plurality of positions of adjustment on said chair.

According to the preferred form of the invention, there is provided a pair of leg frames each having front and rear ground-engaging legs interconnected at their upper ends. A seat is mounted on said leg frames, and a step is mounted on the front legs below said seat. A U-shaped support is mounted on the leg frames above the seat and comprises a pair of laterally spaced arms interconnected at their rear ends by a transverse bight. A back rest is mounted on said bight in a position to the rear of and above the seat. Carried on the arms of the support is a tray having means mounted thereon for slidably supporting it on said arms and releasably locking it in the desired position of adjustment.

Other objects and features of the invention will be come apparent from the more detailed description which follows and from the accompanying drawings, in which:

FIG. 8 is a horizontal section similar to FIG. 7, but showing the tray lock in released position; and

FIG. 9 is an enlarged fragmentary vertical section taken on the line 99 of FIG. 2.

As shown in the drawings, our high chair is supported on a pair of leg frames 10 each formed from a length of metal-tubing bent into a U-shape to provide a front leg 12 interconnected at its upper end by a bight 13 to a rear leg 14. Conveniently, end caps 15 are received over the lower ends of said legs. The pairs of front and rear legs are interconnected toward their lower ends by transverse braces 16 formed from lengths of metal-tubing and having their ends turned downwardly at 17 and bolted, as at 18, to the inner faces of the legs.

As shown in FIGS. 4 and 5, the seat 20 is formed from opposed upper and lower sheet-metal shells 22 and 24 having interfitting peripheral flanges 25 and 26, respectively. A padded covering 28 extends over the upper face of the shell 22 and has its marginal edges bindingly retained between the abutting faces of the flanges 25 and 26. The shells are retained in assembled position by projections 30 formed on the flange 26 and received in recesses 31 formed in the flange 25 and by a plurality of bolts 32. Two rows of loops 34 project downwardly from the lower shell 24. The rows of loops are in fore and aft spaced relationship and support a pair of arcuate rods 35. One of the rods 35 has its ends received in aligned openings formed in the inner faces of the front legs 12, and the other rod has its ends received in aligned openings formed in the inner faces of the rear legs 14 for supporting the seat on the leg frames 10 below the bights 13.

A U-shaped support 36 is carried on the leg frames 10 and comprises a pair of laterally spaced arms 37 interconnected at their rear ends by a transverse bight 38. Conveniently, the support is formed from a length of metaltubing, and the forward ends of the arms 37 are closed by a pair of end caps 39. The arms 37 overlie the leg frame bights 13, and each arm is connected to the adjacent bight by a pair of screws 40 in front to rear spaced relationship. For reasons that will become more apparent hereinafter, a spacer 41 is disposed around each screw 40 to abut the adjacent arm and bight faces for supporting the arms 37 in an elevated position above said bights.

As shown in FIG. 4, the back rest 42 is formed from a pair of opposed front and rear sheet-metal shells 44 and 46 having interfitting peripheral flanges 47 and 48, respectively. A padded covering 50 extends over the front face of the shell 44 and has its marginal edges bindingly retained between the abutting faces of the flanges 47 and 48. The shells are retained in assembled position by projections 52 formed on the flange 48 and received in recesses 53 formed in the flange 47. Said shells are further retained in assembled position and mounted on the support bight 38 by a plurality of bolts 54 extending through aligned openings in said bight and the back rest shells. As shown in FIG. 2, the back rest is mounted on the support 36 in a position above and to the rear of the seat.

A generally rectangular step 56 conveniently formed as a sheet-metal stamping is mounted on the front legs 12 below the seat 20. Said step has a centrally disposed tread 58 constituting the step supporting surface, and upwardly projecting ribs extending along the rear and ends of said tread. A depending peripheral skirt 60 extends around the step and terminates at its lower end in a plurality of inwardly directed flanges 62. The step 56 is supported on the front legs 12 on a hanger having a transverse stretch 64 interconnecting a pair of rearwardly extending lateral stretches 65 projecting rearwardly of the step through interruptions in the flanges 62 and notches 66 in the skirt at the rear corners of the step, The rear ends of the stretches are continuous with a pair of vertical hanger stretches 67 which terminate at their upper ends in outwardly projecting looped fingers 68 bindingly received in openings 69 in the inner faces of the front legs 12 for thus supporting the step on the front legs in a position intermediate the seat 29 and leg braces 16. Conveniently, a second set of openings 69' may be formed in the legs 12 for adjusting the vertical position of the step relative to the seat. The step is retained on the hanger :by the lateral hanger stretches 65 being received between the flanges at the ends of the step and the notches 66 and by an offset 70 formed in the transverse hanger stretch 64 and bindingly retained between the tread 58 and flange 62 along the front of the step.

A sheet-metal tray is carried on the support 36 and comprises a supporting surface having a peripheral depending skirt 76. Said tray has a generally C-shaped configuration and thus includes a central portion 77 and a pair of rearwardly projecting arm portions '78. Mounted on the lower face of the tray in the general area of the arm portions 78 are a pair of brackets, each comprising a web 80 provided with upstanding flanges 82 connected to the inner face of the skirt 76 by rivets 83. As shown in FIG. 9, the bracket Webs 80 are curved, as at 84, to abut the upper outer quadrants of the support arms 37 for slidably supporting the tray on the support 36. A pair of latches 85 are swingably connected to the lower face of the bracket webs 80 by vertically extending pivot pins 86. Each of said latches has tongues 88 and 90 at its front and rear ends. The tongues 88 are swingably supported in channels 91 projecting downwardly from the front end of the brackets, and the tongues 90 are slidably supported in hooks 92 formed at the rear of the brackets. The tongues 88 and 90 are interconnected by a web 92 curved, as at 93, to abut the lower outer quadrants of the support arms 37 when the latches are in their locked position. A wing 94 projects laterally inwardly from each latch for reception in the space between support arms 37 and by frame bights 13. A slot 96 is formed in the inner edge of each of the wings 94 for selective reception around the spacers 41 for locking the tray in the desired fore and aft position of adjustment on the support 36.

In order to releasably retain the slots 96 in locking engagement around the spacers 41, each of the bracket webs 80 has a pair of laterally spaced, downwardly projecting cars 98. A headed pin 99 extends through aligned openings formed in said ears and in a pair of ears 100 projecting downwardly from the latch. The pin 99 supports a coil spring 101 acting between the outermost ear 98 and the innermost ear for opposing outward swinging movement of the latch. Desirably, one of the ears 100 projects below the outermost ear 98 to provide a finger grip for swinging the latch outwardly to release its slot 96 from the spacers 41 to permit the tray to be adjustably moved along or removed from the support 36.

Desirably, hooks 102 are mounted on the bottoms of the tray 75 and seat 20 to permit a crotch strap 104 to be releasably connected thereto.
